Sp. Char. Tail rounded or moderately graduated, the closed wings reaching nearly to its tip. Fourth quill longest; second considerably shorter than the sixth. General color bluish-ash, changing on the nasal feathers, the forehead, sides of head (especially around the eye), and chin, to white. The wings, including their inner surface, greenish-black, the secondaries and tertials, except the innermost, broadly tipped with white; tail white, the inner web of the fifth feather and the whole of the sixth, with the upper tail-coverts, greenish-black. The axillars plumbeous-black. Bill and feet black. Young similar in color, without additional markings of any kind. The gonys, however, convex, and the bill generally more like that of the Jays. Length of male (fresh), 12.00; wing, 7.00; tail, 4.30; tarsus, 1.20.

Hab. From Rocky Mountains to Pacific. East to Fort Kearney, north to Sitka, south to Arizona.

Habits. Clarke’s Crow was first met with by the parties composing the celebrated exploring party to the Rocky Mountains under the direction of Lewis and Clarke. It was described by Wilson in 1811, who was informed by individuals belonging to the expedition that these birds were found inhabiting the shores of the Columbia and the adjacent country in great numbers, frequenting the rivers and sea-shore, and that it seemed to have all the noisy and gregarious habits of the common Crow of Europe.

In his account of this species, Mr. Nuttall states that during his journey westward in the month of July, he first observed individuals of this bird in a small grove of pines on the borders of Bear River, near where it falls into Lake Timpanagos. This was at a height of about seven thousand feet above the sea level, and in the 42d parallel. Their habits appeared to him to correspond with those of the Nutcrackers of Europe.

He afterwards saw a considerable flock of the young birds early in August, in a lofty ravine near the Three Buttes, a remarkable isolated mountain group about forty miles west of the Lewis River. They appeared somewhat shy, and were scattered through a grove of aspens, flying, with a slight chatter, from the tops of bushes and trees, to the ground. He was of the opinion that this species never descends below the mountain plains, but that it has a constant predilection for the pine forests.

Mr. Townsend afterwards found this species abundant on the Blue Mountains of Oregon. He describes its flight as very unlike that of a Crow, being performed in jerks, in the manner of a Woodpecker. At times, when sitting, it is said to keep up a constant scream, in a very harsh and grating voice, and in an unvaried and prolonged tone. He states that it breeds in very high pine-trees, and that he did not meet with it within five hundred miles of the Columbia River.

Mr. Ridgway found this species one of the most abundant birds of the pine forests of the Sierra Nevada. East of this range it was also met with, though only in smaller numbers, in the cedar and piñon woods of the East Humboldt Mountains. He adds that it is a bird so curiously striking as at once to attract attention. It bears but very little resemblance to any bird of its family, and in its general appearance, flight, and notes approaches

so nearly to the Woodpeckers as to be usually known to the settlers as a bird of that tribe.

He further remarks that its flight much resembles that of Melanerpes torquatus, and, as it alights from the top of a tall dead tree, and sits quietly gazing around, it might readily be mistaken for one of the Picidæ. He describes them as being very active in their movements, now flying from a tree to the ground to pick up some article of food, now examining the excavations of an old dead stump or snag, or, on being approached, as flying up and alighting upon the extreme summit of a tree, out of gunshot. It is a very noisy bird, and its notes are harsh and discordant, though less so than are those of the Steller’s Jay, which is generally seen in the same localities. Its usual note is a harsh guttural churr-churr, generally uttered when two or more alight on the same tree. Occasionally an individual takes up a peculiar piping strain, which is immediately answered by all the others in the neighborhood, thus awakening the echoes of the surrounding solitude with their discordant cries. In regard to its nest he can give no positive information, but thinks that they breed in cavities in old dead trees and stumps, having found a nest in such a situation in the East Humboldt Mountains, which he thinks belonged to a pair of these birds which were flying about, and seen to enter this cavity.

Dr. Newberry, in his Report on the zoölogy of his route, states that he found this species rather common along a large portion of it, and was thus enabled to study its habits at leisure. He found it strictly confined to the highlands and mountains, never, where he saw it, descending to a lower altitude than about four thousand feet. On the other hand, while crossing the Cascade Mountains at the line of perpetual snow, seven thousand feet above the sea-level, he has seen this bird, in company with the Melanerpes torquatus, flying over the snow-covered peaks three thousand feet above him.
